Idea

I think it's extremely strange that we can't Query a Single Item. I couldn't believe it so i searched the API documentation Multiple times because i thought i was missing something.

In Order for Dedicated Servers to Validate Entitlement , We have to Get All the User Inventory Of Hundreds of Items Iterate Through each one and Find the One with the ID for just a Simple Entitlement check. we have to do it for 10 Players per match so it'll add up to a lot of query.

Economy v2 supports filtering your GetInventoryItems request: https://learn.microsoft.com/en-us/rest/api/playfab/economy/inventory/get-inventory-items

"Filter": "Id eq '{ItemGuIdHere}'"

See https://learn.microsoft.com/en-us/gaming/playfab/features/economy-v2/catalog/search#filter for more info.

With the Economy V2 GA release, you can query by 'type', 'id', and 'stackId'. This should allow you to get one or more items from the inventory that match your Filter query.
